Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as aluminum electrochemical capacitors, are polarized capacitors with one of their electrodes being aluminium in the shape of foil with a larger surface area than the other electrode, which is a paper or plastic material impregnated with a conductive electrolyte. They are one of the most popular types of capacitors available on the market today and have a wide range of applications.EKZN160ELL472MM20S is a type of aluminum electrolytic capacitor with a rated voltage of 160V and a capacitance of 472μF. It is generally used in applications requiring the filtering or decoupling of AC power or signal sources. This type of capacitor is widely used in the automotive, clean energy, consumer electronics, power supplies, motor control, and telecommunications industries.The working principle of aluminum electrolytic capacitors is based on the fact that the anode of the capacitor is made from an aluminum sheet. When a voltage is applied across the capacitor, it will cause ions from the electrolyte solution to form an insulation layer on the aluminum surface, forming two layers of "electric charges" on the aluminum foil. One layer is called the positive electric charge layer and the other layer is the negative electric charge layer. The positive charge layer attracts electrons from the electrolytic solution, forming the dielectric of the capacitor, while the negative charge layer attracts positive ions, forming the capacitance.The two layers of electric charges attract each other, creating an electrostatic field with electric potential. This electrostatic field forms the capacitance of the capacitor and stores the electrical energy. Since the capacitance is formed by two layers of electric charges, aluminum electrolytic capacitors are called polarized capacitors. The anode of the capacitor should always be connected to the positive voltage terminal, while the cathode should always be connected to the ground or negative voltage terminal.The main advantage of aluminum electrolytic capacitors is that they have a high capacitance in a small package, making them ideal for a wide range of applications such as power supply filtering, signal decoupling, and motor control. Additionally, they are highly reliable and have a long life expectancy. The life span of an aluminum electrolytic capacitor is typically higher than that of any other type of capacitor, usually ranging from 2000 to 4000 hours.In conclusion, aluminum electrolytic capacitors are an essential component in many electronic circuits, from consumer electronics to automotive applications. They are inexpensive, highly reliable, and have long lifespans. EKZN160ELL472MM20S is a type of aluminum electrolytic capacitor with a rated voltage of 160V and a capacitance of 472μF, and is widely used in filtering or decoupling applications. It is important to remember to connect the anode of the capacitor to the positive voltage terminal, and the cathode to the ground or negative voltage terminal.
